Absolutely none what so ever. Probably should have mentioned that.
Since I was once in your "shoes," I'll give truthful advice.
If you just want to learn the "conceptual nature" of Quantum physics, read all the "general public" books you can find on the subject. There are many good, non-mathematical books on the subject. John Gribbin's "In Search of Schrodinger's Cat," Feynman's QED, maybe even his "6 not so easy pieces."
There are plenty of books that paint a very enjoyable picture on the subject.
If you "really" want to learn quantum physics, you need to boost your Math and Physics background. Gerard 't Hooft has a site:
http://www.phys.uu.nl/~thooft/theorist.html that literally allows you to go from layman to physicist without ever leaving that site. Expect to spend the better part of a decade with that site on your computer though.
I'm not a Quantum "expert" by any means, but here is what I'd recommend as a potential quickest path to really "learning" Quantum mechanics.
Basic Math: (you probably have at least some understanding of all of this and could get a decent "grasp" over a weekend of hard studying)
Geometry
Algebra
Trigonometry
Beginnings of "cool" maths:
Calculus (differential and Integral)
-I used "teach yourself Calculus" by P. Abbott to literally "learn" Calculus in a week.
You can use a book like Mary Boas' "Mathematical Methods in the Physical Sciences" to cover just about everything else you'll need.
Physics prep:
Get at least a "grasp" of all the Physic concepts from a book like Halliday or Serway's textbooks.
Quantum:
Start with a basic "Modern Physics" book like Tipler's, Serway's, etc., etc
By that point you won't need to ask where to go next, you'll know what you want to focus on.
If you are highly motivated, intelligent and focused, I would say you could cover all of this in a year. You'll find out very quickly if you "really" want to learn quantum.
